CAR-DOOR RETAINER.

SPECIFICATION forming part o1' Letters Patent No. 336,019, dated February 9, 1886.

(No model.)

To @ZZ whom it may concern:

Be it known that I, ANTHONY RoELoFs, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Car-Door Retainers, ofwhieh the following is a specification.

My invention consists in the adaptation to a hasp-fastening of the main principle of the car-door retainer forming the subject of my Letters Patent No. 329,340, dated October 27, 1885, the manner of carrying out my present invention being fully set forth hereinafter.

In the accompanying drawings, Figure l is a sectional perspective view of part of the frame and door of a railway-car with my improved door-retainer; Fig. 2, asectional plan view of the same; Fig. 3, a vertical section, partly in elevation, on the line 1 2, Fig. 2; Fig. 4, a face View; Figs. 5 and 6, perspective views of parts of the device, and Figs. 7 and 8 views illustrating modifications of the invention.

A represents one of the posts of the doorframe of the car; B, part of the sheathing of the ear-side; D, part of the framing of the door, and E part of the planking of the latter, F being the jamb against which the door strikes when closed. Passing through this jamb, through the sheathing B, and through the post A is a bolt, J, having at the outer end a head, a, the inner threaded end of the bolt being adapted to a nut, b, which is contained in a recess in the post A, so as to be prevented from turning therein. The inner end of the bolt is enlarged, or has its thread battered, or is otherwise so constructed that the bolt cannot be unscrewed from the nut, such move ment of the'bolt in the nut being permitted, however, that a slight movement of the head a ofthe bolt from and toward the face of the jamb F is permitted.

Hung to a staple, d, on the door is a hasp, K, the end of which is slotted for adaptation to the stem of the bolt J, as shown in Fig. 4, so that when said bolt is screwed up to its full extent the end of the hasp will be contined between the head a of the bolt and a plate, f, secured to the face of the jamb F.

The friction between the face of the hasp and the inner side of the bolt-head a may be relied upon to prevent the raising of said hasp, so as to free it from the control of the bolt; but

for additional security I prefer to provide the plate f with a lug or tlange, g, which overlaps the hasp and prevents the elevation of the same until the bolt has been so far unscrewed as to permit lateral movement of the hasp to an extent suiiicient to free it from the control of the flange. Then the bolt is screwed up by a wrench or other suitable implement, the head of the same bears with such force against the face of the hasp, and the threads of the bolt are jammed so tightly against those of the nut that the bolt cannot be unscrewed eX- cept by the use of a proper implement, the access oi' tramps or yard-thieves to the car being thus prevented, while the mutilation of the side oi' the ear by the nailing ofthe usual batten thereon is effcctually overcome, as in the patented device.

"When the use of a swinging hasp is not desired, the hasp may be slotted at the end and provided with a catch, g', for engagement with the jamb F or its plate f, as shown in Fig. 7, and, if desired, the arrangement of bolt and nut shown in Fig. l may be reversed, the head of the bolt being adapted to the recess in the inner side of the post A, and the nut being adapted to the outer threaded portion of said bolt, so as to bear upon the hasp, as also shown in Fig. 7.

A hasp hung to the carside may in some cases be used in combination with a bolt and nut carried by the door, as shown, for instance, in Fig. 8; but the construction shown in Fig. l is preferred.

The staple (l, as shown in Fig. 5, has but one prong for entering the door, said staple forming part of a plate, h, which can be secured to the face of the door by suitable screws, so as to provide for the more secure attachment of the staple than when it has two prongs driven into the door in the usual manner.

I claim as my invention- 1. The combination ofa car-door and doorframe with a bolt and nut carried by one of said parts and a hasp carried by the other part, and so constructed as to be clamped by the bolt-head or nut, all substantially as specitied.-

2. The combination of a car-door and door frame, a bolt and nut carried by one of said parts, a hasp carried by the other part, and so IOO constructed as to be clamped by the bolt-head plate between which and the head or nut of 15 or nut, and a catch-lug, whereby the release the bolt the hasp is confined, said plate havof the hasp is prevented until the bolt or nut ing a lug, whereby the removal of the hasp is l has been par ially o11 wholly unsorewed, all prevented until the bolt or nut is partly or 5 substantially as specified. wholly unserewed, all substantially as speci- 3. The combination of a oar-door and doorfied. t 2o frame, a bolt and nut carried by one of said In testimony whereof I have signed my name parts, and a hasp carried by the other part, to this speoication in the presence of two subslotted for adaptation to the bolt, and clamped Soribingwitnesses.

Io by the head or nut of said bolt, all substan- T many as Specified. ANTHOLY ROELOFS.

4. The combination of a car-door and door- Titnessesz frame, a bolt and nut carried by one of said WILLIAM F. DAVIS,YY parts, a hasp carried by the other part, anrdit HARRY SMITH.
